▎ 摘　　要

An imidazolium-modified hexa-peri-hexabenzocoronene derivative (HBC-C11-MIM[Cl-]) was designed and synthesized as a stabilizer to fabricate reduced graphene oxide (RGO). The resulting RGO/HBC-C11-MIM[Cl-] hybrid shows excellent dispersivity (5.0 mg?mL-1) and stability in water. RGO/HBC-C11-MIM[Cl-] was comprehensively characterized by using atomic force microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, thermogravimetric analysis, and Raman spectroscopy, thus revealing that one HBC-C11-MIM[Cl-] group can stabilize about 178 carbon atoms on the graphene sheets. The obtained hybrid film exhibits a high conductivity of 286 S?m-1. Furthermore, the HBC-C11-MIM[Cl-]-modified RGO sheets can be readily dispersed in polar organic solvents upon exchange of the hydrophilic Cl- ions for hydrophobic bis(trifluoromethylsulfonyl) amide (NTf2-) ions.
